ROPE-T HIMBLE To all 'whom t may concern.

Be it known that A I, CHARLES LAND, a citizen of the United States, residing at Trenton, county of Mercer, and State of New Jersey, have invented certain new and useful Improvements in Rope- Thimbles, fully describedv and represented in the following specification and the accompanying `drawings,forming a part. of the Saule. ,fl l

This invention relates" to an improved thimble for use with wire ropes, the object being to provide astrong and simple thimble which is lreadily connected to or disconf nected from hook eyes orsiinilar closed'con- The thimble is intended espeeially for use in wire rope slings, where it enables a drop forged hook to be used with integral closed eye, thus avoiding the necessity' for a separate ring toconnect the thimble to thehook eye, but the invention is of general application with rope'thimbles.

. In the accompanying drawing, forming a part of this specification, there isshown a rope thimble embodying all the features of the invention in their preferred formas l applied to wire rope slings and the` like, and

this construction will now be described in detail, and the features forming the invention then--speoiically pointed out in the, claims.

ln the drawing Figure 1 is a side View of the rope eye, with the thimble in place, and shown partly in section;

Figs. 2, 3 and et are sections on, respectively, the linesl 2 2, 3 3, andv 4 4 of Fig. 1. l

Referring to the drawings, the thimble or ey' piece is formed of two section-s A, A divi ed longitudinally of the thimble and secured together by rivets, bolts or like securi of section A', and the tongue 5 of section A ing means 10 through the bodies of the two sections, so as toform the usual groove for receiving the rope X. The section A is open at its outer end as at 2, and section A is open at the inner end as at 3. These openings are filled by tongues formed integrally with the sections, the tongues being' of such size as -to lit snugly within the vopenings and completely lill the same, vthe tongue 4 .of section A entering and closing the open end 3 entering and closing the open end Q of seotien- A. The two parts of the thnnble are C; Sunbascured by rivets 1 to hold the posite ends.

. -preferably provided at their inner end 'with studs 12, 13 outside the rope groove`, th'ese .studs extending -in opposite vdirections from the lparts A, A-, and overlappin l so'as to form. a ring by which the rope is held in place. These studsprefer'ably' are wedgesliaped for tightness, as shown, and are preferably secured together for strengthening thethimble, being shown as provided with holes`through which,pass pins 11 sestuds and thimble parts together. f

In addition,4 tos-the overlapping studs, 12, I

13, for'holding the two parts of the thimble from shiftingon each other-'under rope tension, the two partsvA, A preferably are proi vided with corresponding recesses and Studs.

14, 15 on opposite sides of the thimble, so

.that the shoulders on these engaging studs and recesses aid in strengthening the thimble against the ropetension. A The thimble may'be used without any means at the outer end of the thimble for holding the rope in the thimble :roovef,` but preferablyv they two partsvof the thimble A, .A are provided with overlapping ears 16 for holding the rope in place, as vusual in other thimbles. The thimble shown is especially adapted forwire rope 'slings or other uses Where the equalization of tension on the two` parts of the rope loopv is important, and for this. purpose the thimble is such that the rope is free to slide on 'the thimble under strain Awhile'ofgreat strength and resistance to change of form,

The hook eye or other similar member is readily applied to the thimble by passing the eye through the open end of one of the thimble sections, then through the open .end

ofthe .other thimble section, and then' securing the sections together. The provision of the tongues entering and closing the open ends has greatly strengthened the thimble and provided for Astrengthening of those parts most liable to wear and breakage.

It is 'not intended that the invention shall` belimited to the specific form shown in the drawings, as detail. changes may be made .without departing from the invention as de- Afined bythe claims.

What is claimed is:v

the line of division being longitudinally of the thimble, and the parts being openat op- 2. Arope thimble lconsisting of two parts,

` v105 l1. A ropethimble consisting o f two parts, i

the line of division being 'longitudinelb7 of y the thimble, eech'p'art being open at one end and havinga tongue portion at' theother' end, the tongue on one part being adapted 5 to enter and close the open end of the other part. f 3. Arope thiinble consisting of two parts,

' the line of division being longitudinally; through therope groove, each part being '10 l`open at one end and having a tongue at the A vopposite end,. the `open end and the tongue of the one-part being at oppositeendsto' the open end and tongue of the other fpart, .the .tongues being adapted to enter and close the 15 open end-s,- overlapping studs on the two pzirts'acting to hold the two parts against slip on each other, and means for securing the two parts together to form e thilnlole.`

' 4.- A rope thimble consisting of two parts 20 A, A', the line-ofl division being longitudinell)T th'roughgthe' rope groove, each part' `hmfing vrespe'etively;'open ends 2 and tongue portions 4 and 5, overlapping studs 12, and 13 at the inner end of the thimble nelly through the rope groove, each' part hav-ing respectively open ends 2 end 3, tongue portion-s 4f 'and v5, overlapping studs 12,',and 13 at the inner end of the thirnble outside the grooves having openingsin line,

looking 'pin 1.1 passing tlircmgh.seidv openings, and 4corresponding recesses and studs 14 :1nd l5 on the two'perts 'of the thirnble'l j between its endsl .1n testimony whererf, I have hereunto set my hand.
